Eli Friedman 8174f2c23c Work-in-progess rewrite of thunks: move thunk generation outside of vtable 
generation, and make sure we generate thunks when the function is defined
rather than when the vtable is defined.

llvm-svn: 90722
 2009-12-06 22:01:30 +00:00
Anders Carlsson fe5f7d916f Set the correct linkage for VTTs as well.

Anders Carlsson 232324c5c0 More linkage improvements. 
llvm-svn: 90687
 2009-12-06 00:53:22 +00:00
Anders Carlsson 0911ae8ef2 Pass the desired vtable linkage to GenerateVtable directly. Only call MaybeMarkVirtualImplicitMembersReferenced for non-inline functions.

 2009-12-06 00:23:49 +00:00
Anders Carlsson 7e28c5f2e2 Make GenerateVtable a private member function of CGVtableInfo.

 2009-12-06 00:01:05 +00:00
Anders Carlsson 4ed44eb7d9 Only emit the vtable definition if the class has a key function and we're emitting it, or if the class doesn't have a key function and we are emitting the complete constructor. 
llvm-svn: 90681
 2009-12-05 22:42:54 +00:00
Anders Carlsson 0ab79e22ab If a class does not have a key function, its linkage should be weak_odr. 
llvm-svn: 90680
 2009-12-05 22:24:38 +00:00
Anders Carlsson 58b271d450 Use createGlobalVariable for creating vtable variables too.

 2009-12-05 17:04:47 +00:00
Eli Friedman 6c08ce7706 Skip actually generating the vtable unless we are defining it. This avoids 
the side-effects of generating the methods in the vtable (including PR5676).
